Recommended fix for HBKII belt slipping off flange bearing?

[Jetskeeter]

does anyone know what the preferred fix would be for the belt slipping off the left hand flange bearing guide? Since I upgraded to brushless motor this problem has surfaced. thanks

:roll: I placed a couple of thin washers between the flange washer and the frame effectively lowering the flange bearing and that seems to work. I tested it at max throttle with the blades off and the belt stayed in place. Haven't flown it yet due to high winds.

Try putting some lubricant inside the boom. It will stop the belt tangling inside. But not too much otherwise it might slip.
